Abstract
A control method is used for an elevator. The elevator includes an enclosure located at each floor, two doors mounted to the enclosure, and a control unit to control the doors to open or close. The control method includes, capturing an image of a scene in front of the doors by a camera. Checking the image to determine whether there are people in front of the doors, and outputting a first control signal to the control unit to stop closing the doors upon the condition that there is a person in front of the doors.
Claims8
A control apparatus for an elevator, the elevator comprising an enclosure located at each floor, two doors mounted to the enclosure, and a control unit to control the doors to open or close, the control apparatus comprising:
- a depth-sensing camera mounted on the enclosure above the doors, to capture an image of a scene in front of the doors and obtain data about distances between a plurality of points in the scene and the depth-sensing camera;
- a processing unit connected to the depth-sensing camera;
- and
- a storage unit connected to the processing unit and storing a plurality of programs to be executed by the processing unit, wherein the storage unit comprises:
- a three dimension (3D) model building module to build a 3D model of the scene according to the image of the scene and the data about distances between the plurality of points in the scene and the depth-sensing camera;
- a human detection module to check the 3D model to determine whether there is a person in front of the doors;
- and
- a calculating module to output a first control signal to the control unit to stop closing the doors upon the condition that there is a person in front of the doors.
